Tire Dilema

Hi Folks,
I have held back long enough, I have read more tire posts and discussions than I wanted to. I want to put new tires on our 2013 Montana High Country. The weight on the 6000# axles is 8700# loaded and ready to roll. I was going to go with Saliun 235/80r/16 and be done with it. They are on back order for 3 weeks. Leaving for AZ. middle of Sept. I am looking at Geostar 574 235/85r/16 and Bridgestone Durvis r250 LT 235/85r/16. There is about $500.00 price difference between the two.(for 5 tires)
Since everyone on this forum is well versed on tires. what are your opinions?

Thanks for your help

I have used Michlien LT tires for 10 years. Never had a any problem in around 90,000 miles. As long as weight is okay, I would go with the LT tires.

Firestone TransForce is another option, for a LT tire, never had a blowout or tire issue with them.

I had the Bridgestone Durvis on my other 5th that was another brand. It weighed about 12000 pounds. Had them on for 3 years before I sold it and bought the Montana I have now. Never had any problems during that time. I put the G 14's on this one because it is even heavier than my other one was.

Michelin LT MX4's here. Opposed to some on the MOC ... I don't see the need to replace the spare with an upgraded tire. I consider a spare just that ... a spare. It'll get me to a place to buy new or repair my flat and that's all I require of it. The spare wheel is steel ... the other 4 aluminum, so it will have to come back off at some point anyways unless the looks don't bother you. These are not drive axles and the tire diameter difference if any is irrevelant.

I have Michelin XPS Ribs on mine. But I agree with dieselguy on the spare. Mine has never touched the ground. Nor the spare on my last two trucks. And the truck before that only once for about 20 miles. And I can't even remember using the spare on any of the DW's vehicles.

The HC's with their 6K axles and 6 lug wheels represent the dilemma members faced back when the biggest Montana came with 6K axles. The ST's would blow and there were many, many questions about what to replace them with.

There is a MOC member Lonnieb who is a tire dealer and a great guy. A number of MOCers traveled to his shop in Texico, New Mexico to buy tires due to his participation and advice here. While he hasn't been active on the forum recently, he was a real tire guru who always tried to help members with their tire questions. He made what I consider the definitive post on LT v. St tires back in March 2013. He re-iterated the advice numerous times here in different postings. Here is the pertinent posting:

Quote:
quote::By Biggjb

Lonnie, I have a 2009 2980RL and currently have GY Marathons ST235 80R16 E rated. Fully loaded it is 14400 lbs. I always ensure the tires are 80 psi and check that every morning while on the road. I had one blow-out last year on a very short haul, and I have just went over 1200 miles with no mishap. But the concern of a blow-out on the I-95 was constantly in the back of my mind. I have heard LTs would work better.
The specs I came up with for your trailer are as follows;

Dry shipping weight - 10,415 lbs.
Cargo carrying capacity - 3,940 lbs.
Pin weight - 2,275 lbs.

Adding the dry shipping weight and the cargo carrying capacity together I get 14,355 lbs., which is pretty close to what you listed. Subtracting the pin weight from 14,400 I come up with 12,125 which calculates out to 3,031 pounds per tire.

The most common LT size to replace the ST, is LT235/85R16. This size is approximately one inch larger in diameter and the same width as the ST235/80R16 you are currently running. Another size would be LT245/75R16 which is three tenths inch shorter and four tenths inch wider than what you currently have. Both of these sizes, in the E load range, have a maximum load rating of 3042 pounds at 80 psi. I know this looks like you would be pushing the limits, but that isn't the case. Unlike the ST rated tires, the LT has a large reserve capacity built in, meaning the maximum load rating on the tire is significantly less than the tires actual capacity. This is done due to Federal regulations because these tires must safely carry human passengers at speeds up to 112 mph. ST rated tires are not held to the same safety standards for several reasons, they are NOT legal on motorized vehicles, they are NOT legal at speeds above 65 mph, and most importantly, they are NOT legal to carry human passengers at ANY speed.

A good quality, name brand LT tire, in the E load range will serve you well. Below is an updated list of my personal preferences, along with a "ballpark" price, not including installation. Prices vary across the country, and even from dealer to dealer, so shopping around a little would be a good idea. I recommend going to a REPUTABLE dealer, one that sells a lot of tires, one whose main business is tires.

LT235/85R16E

1. Michelin XPS Rib - $314.00 each.
2. Bridgestone Duravis R250 - $250.00 each.
3. Bridgestone Duravis R500 - $206.00 each.
4. Firestone Transforce H/T - $162.00 each.
5. BF Goodrich Commercial T/A - $188.00 each.

Lonnie's Post is on Page 2 of this link

I am sure the prices are not current, but the recommended tires are.

Same here. Any US made LT tire will be better than any ST made in China.

I am very satisfied with my Sailun's, (16" tires) have you checked at more than one place? I am sure some of the other tire brands are fine but I will say that I have piece of mind with my Sailun's even if I am going 70/75 MPH. They are speed rated for that speed and at times I will go that speed while pulling the Montana.

Good Morning everyone,
I have called 4 tire shops in the area, they all tell me the Saliun's are on back order.
Good idea on not replacing the spare. With good tires, the spare just might never touch the ground. After thinking about it, I have never used the donut spare in any of my cars. Once I get the Power King China bombs off I will feel better. Even though they only have 1000 miles on them I just don't trust them !

I have successfully used a set of Michelin LT tires for 5 years but when they "age out" I will be replacing with Sailun 637s.

2014 mon. high country 305 RL. Replaced original Tow Max tires with FirestoneTransforce 235/85R-16s due to failure of all 4 original with about 3000 miles on them. Like the Transforce but yesterday while checking springs, suspension,etc. I noticed all 4 tires have hit the top of the fender well area and exposed the plywood. As these tires are only 1" dia .larger or only 1/2" taller above the hub I thought clearance would not be a problem. Would appreciate it if some of you who have put on the larger tires would look and see if yours are hitting the top of the well. The OP might want to see if others have this problem before going larger.

For 6000 pound axles there is no tire better than the michelin xps ribs. They come in the 235x85x16 10 ply and they are all steel like the 14ply sailuns.They weigh the same as the sailuns also.

Have Michelin tires on my car, truck and 5th wheel. Had XPS tires on my 2880 2001 trailer. No problems with any of them. I finally bought a new spare for my 2007 Chevy which was 9 yrs old and didn't feel I could trust the spare if I had to drive any distance. Bought 5 tires when I replaced the Marabombs half way across U.S.when I had a blowout with the Marabombs. Truck tires are 5 yrs old and will probably replace with a cheaper tire as we may be traveling less and maybe for another 5 yrs.

I am 100% pleased with my Bridgestone Duravis R250 tires.

Like do you like Ford or Chevy. But with a 102mph speed rating, they are working for me.

6000 pound axles. You High Country owners talking about 6000 lb.rated axles, are you sure that is what you have? My 2014 HC came with 5200 lb. axles. Will be calling Customer Service Monday to check this out.
